Organizing And Communicating Health: A Culture-Centered And Necrocapitalist Inquiry Of Groundwater Contamination In Rural West Bengal, Parameswari Mukherjee Jun 2023

Organizing And Communicating Health: A Culture-Centered And Necrocapitalist Inquiry Of Groundwater Contamination In Rural West Bengal, Parameswari Mukherjee

USF Tampa Graduate Theses and Dissertations

As a discursive point of praxis, this dissertation project seeks to record knowledge from below around the overlaps between health, water and health interventions emerging from rural communities located in North 24 Parganas and Purulia in West Bengal that are disproportionately impacted by water-insecurity. My dissertation also documents how multiple-stakeholders such as local NGOs, international NGOs, non-profits, and donor agencies organize access to safe water and health interventions for the water-insecure communities located in North 24 Parganas and Purulia. The integration of the CCA and necrocapitalism afford theoretical and methodological guidance in this dissertation to help document the localocentric stories …

Calculating And Comparing Bioaccessible Lead Concentrations In Soils From The Garfield Ridge, West Elsdon, And Lakeview Community Areas Using A Pbet And A Mehlich-3 Digestion Method, Emma Sznewajs Jun 2023

Calculating And Comparing Bioaccessible Lead Concentrations In Soils From The Garfield Ridge, West Elsdon, And Lakeview Community Areas Using A Pbet And A Mehlich-3 Digestion Method, Emma Sznewajs

DePaul Discoveries

Lead exposure through soil poses potential health risks to those in areas with higher soil-Pb levels, specifically urban areas. The soil-lead concentrations recommended by the EPA are based on measurement of total lead concentration, yet only a percentage of the total lead can actually be absorbed into the body. The percentage of lead in soil that can be absorbed into the blood through ingestion is reffered to as bioaccessible lead and can be a more accurate way of measuring potential dangers of lead in soils. This study measured the amount of bioaccessible lead in the community areas of West Elsdon, …

Equilibrium And Kinetic Studies Of Crude Oil Sorption On Unmodified And Modified Napier Grass, Amalachukwu Ifeyinwa Obi, Vincent Ishmael Ajiwe, Chinwe Priscilla Okonkwo Jun 2023

Equilibrium And Kinetic Studies Of Crude Oil Sorption On Unmodified And Modified Napier Grass, Amalachukwu Ifeyinwa Obi, Vincent Ishmael Ajiwe, Chinwe Priscilla Okonkwo

Makara Journal of Science

Nowadays, natural organic adsorbents are widely used to clean up oil from spills owing to their effectiveness, affordability, and biodegradability. In this study, Napier grass, a widely available agricultural material, was used to remove crude oil from aqueous media. The Napier grass was modified via a mild acetylation process to improve its hydrophobicity. The modification increased the Brunauer–Emmett–Teller surface area of the grass from 180.07 to 271.13 m2/g. Fourier-transform infrared analysis revealed that the modification endowed the originally hydrophilic Napier grass with hydrophobicity. The oil sorption processes were based on monolayer physisorption and controlled by film diffusion. The …


Not-So-Super Superfund: Cercla’S Biggest Issues, Cameron Berthiaume Jun 2023

Not-So-Super Superfund: Cercla’S Biggest Issues, Cameron Berthiaume

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal

The Comprehensive Environmental Response, Compensation and Liability Act (CERCLA/Superfund) is a federal law that allows the Environmental Protection Agency (EPA) to clean up contaminated sites and hold the parties responsible for the contamination financially liable. However, CERCLA faces a number of challenges to fulfilling its mission. This report examines some of the biggest issues facing the law in the past and present.

Preliminary Evidence Of Anticoagulant Rodenticide Exposure In American Kestrels (Falco Sparverius) In The Western United States, Evan R. Buechley, Dave Oleyar, Jesse L. Watson, Jennifer Bridgeman, Steven Volker, David A. Goldade, Catherine E. Swift, Barnett A. Rattner Jun 2023

Preliminary Evidence Of Anticoagulant Rodenticide Exposure In American Kestrels (Falco Sparverius) In The Western United States, Evan R. Buechley, Dave Oleyar, Jesse L. Watson, Jennifer Bridgeman, Steven Volker, David A. Goldade, Catherine E. Swift, Barnett A. Rattner

United States Geological Survey: Staff Publications

Although there is extensive evidence of declines in the American Kestrel (Falco sparverius) population across North America, the cause of such declines remains a mystery. One hypothesized driver of decline is anticoagulant rodenticide (AR) exposure, which could potentially cause mortality or reduced fitness. We investigated AR exposure in wild American Kestrels in Utah, USA. We collected and tested for AR residues in liver samples (n = 8) from kestrels opportunistically encountered dead and in blood samples (n = 71) from live wild kestrels, both nestlings and adults. We found high detection rates in both tissues. Adult …
